Jets first-round pick Muhammad Wilkerson injured his hip yesterday and sat out the team portion of practice. A Jets spokesman said the defensive end could have returned to the field but was held out for precautionary reasons. It was not clear which hip he injured.

Wilkerson, the No. 30 pick overall out of Temple, has had a strong start to training camp. So much so that Jets coach Rex Ryan said Wilkerson will be a starter. The Jets will not practice today, so Wilkerson will have an extra day to heal. The team’s first preseason game is Monday in Houston.

Wide receiver Plaxico Burress
sat out team drills again yesterday as he recovers from rolling his left ankle last week. Burress has yet to go through a full practice with the Jets.

“I’m just trying to avoid that big setback,” Ryan said, “but he is doing more and more.”

Tailback Joe McKnight
(ankle) also sat out team drills.

Jets defensive coordinator Mike Pettine
was asked how long it took for him to get over the team’s 24-19 loss to the Steelers in the AFC Championship Game in January.

“Are you making the assumption that I’m over it?” he said.

Pettine talked about how tough it was to watch the tape, particularly the first half, when the Steelers rolled to a 24-0 lead.

“Here we came out, coming off an emotional win [over the Patriots], and as a unit we were flat for a half,” Pettine said. “To me, you can’t justify that. Here you are in the biggest game and you’re one game away from the ultimate and we were flat. We were uninspired. That’s hard to take.”

Training camp has been different for the Jets this season, at their headquarters in Florham Park, N.J., instead of Cortland, where they went for camp the past two years. Players are also adjusting to the new setup where there are no two-a-day practices.

“It don’t even feel like camp,” cornerback Antonio Cromartie
said. “To be honest with you, I hated that they took two-a-days away. I think two-a-days were the best for our mental aspect.”

Safety Jim Leonhard
sported a fake tattoo on his right leg during the morning walkthrough to poke fun at Ryan’s new tattoo. . . . Practice was moved indoors yesterday due to the weather. . . . Rob Turner
is now working at starting right guard with Brandon Moore
(hip) still unable to practice. That allows Vlad Duccasse
to get more reps at right tackle, where he will back up Wayne Hunter
. . . . It’s still early, but Nick Novak
has looked more impressive than incumbent Nick Folk
in the kicking competition.
